TRUCK.

. To all/whom it may concern:

Be it known that I, NICHOLAS E. HmsoH, a citizen of the United States,residing at Wilmington, in the county of Newcastle-and State ofDelaware, have invented certain new and useful Improvements in Trucks,of which the following is a specification.

This invention relates to trucks for rail-' way cars, and has for its,princi al object the'provision of means for sustaining and equallyapportioning the weight of the car and its contents when subjected toits full capacity.

as will 'Another object of my invention is to .pm-

In loading a car to its full capacity, it often happens that a lowcoupling is the result; in which event the relative safetyof suchcoupling is greatly reduced.

It is the object of this invention to overcome this danger, ciallydesigned side frames, ster and equally disposed sustaining springs, morefully appear hereinafter.

.vide a bolster and side frames which can be readily assembled withoutthe use of many bolts, rivets and the like.

I A furtherobject of this invention is the 7 provision of side frameswhich will permit the brake levers to operate upon the outside of thetruck, so that when trouble does occur it can be readily repaired,without .going under the car. i H

lVith these and otherobjects in view,the invention consists in the novelarrangement and combination of parts hereinafter described and pointedout in the appended claims.

In the drawings-Figure 1 is a side elevation of my improved truck; Fig.2 is a plan view thereof partly broken away; Fig. 3 isa detachedperspective view of theside frame and one end of the bolster whichinterlocks therewith; Fig. 4 is a detail horizontal sectional", viewthrough the side frame, on the line 14 Of Fig, 1 with .the bolster inplace; and Fig. -5 is asi-milar view on the line 55, ofFig. 3, with thebolster in position therein.

. Referring to the drawings, the truckconsists of a pair of side frames,the bolster, the usual journal boxes,

in the providing of espe connecting 'boltiea ar and h the topand lowerarch bars and column ports, and an intermediate arch bar, the latterbeing interposed for greater spring sustaining strength, as will morefully hereinafter appear.

l -he side frames 1 are identical in structure, and-are composed of anupper arch bar 2, a .lower arch bar 8 and an intermediate arch bar 4.The lower arch bar 3 -is provided with a supporting surface or platform5 at the center thereof, and receives a pluralityof springs 6; and theintermediate arch. bar 4 is similarl intersected by a supporting surfaceor ,p atform 7 and receives a plurality of springs 8. These supportingsurfaces 5-and 7- are larger in area than the arch .bar sections, in.order that they may support a set of four standard springs each.vExtending from the lower arch bar to the upper arch bar, andintersecting the intermediate arch bar are the columns or posts 9 ateither side of the plat-form surfaces.

These columns are of web sections and provide substantial strengtheningmediums for the three arch bars. of-each column, beneath the upper andintermediate arch bars are vertically arranged lugs or tongues 10 the,purposes of which are to fit within corresponding recesses or groovesformed upon the bolster, to be described presently. The side frames-arefurther formed with the'strengthening web sections .12 which are formedalong the upper side oil-the lower arch bar, and extend vertically andintersect the intermediate and upper arch bars. The ends of the sideframes are of substantial metal and are secured to the upper side, ofthe journal boxes 13.

Suitable tie bars '14 are secured to the underside ,of the lower archbar and the under .side of (the journal boxes. The journal boxes act asstruts between the ends. of the side frames and the tie-bars, near theirouter ends, and all of these parts-are united by journal box bolts 15passing through the several members and providedwith nuts on their lowerends. The tie-bars may, however, continuously extend under the lowerarch her. i desi ed Patented J line-2a, i913. ApplicationrfiledAugust-24, 1912. .Serial No. 116,896.

Upon the inner sidester 16, provided with the usual center Connectingthe side frames'l, is the lpolate 17 and near each end the truck sideearings 18, all of these parts being cast irate-- gral with the bolster.

The bolster is of the li-beam type, its lower surface being slightlyarched. At

- each end, the web section is cut'away as at 19, and both of its upperand lower surfaces are extended parallel and formed in the shape ofchannel beams. Recesses or grooves 20 are provided in these latterchannel beam-sections and receive the lugs or tongues 10 formed on thecolumns of the side frames.

In interlocking the, side frames upon the bolster ends, they are firstslid onto the same, until the lugs register with the correspondingrecesses formed in the ends of the bolster, when the side frame isallowed to drop securely into place, as shown in Fig. 1. .The springsare now interposed in their respective pockets, there .beingeightarranged porting surfaces upon each side of the truck within the supofeach side frame. From the present arrangement of bolster and side frameswith their spring supporting or platmediate arch bar is a slot 21,through which the brake levers 22 pass. A link 23 connects these leversupon the outside of the side frame, so as to operate the brakes inunison.

The openings or slots 21 formed in the columns of the side frames,constitute guides for the levers and direct their positive operationagainst undue torsion that is exerted when the brakes are applied. Inproviding this particular form of side frame, adapted to accommodate andguide the brake levers, an efficient safety precaution is included,whereby the danger of going under the car for repairin purposes, iseliminated. Thus, it will beo yious that a side frame is designed inwhich the additional intermediate supporting ar'ch bar increases anddistributes the weight of the car when loaded, to its full capacity; andalso one in which the column posts act as substantial guides for thebrake mechanism, thereby increasing the safety of the truck throu hout.

Having thus fully descri ed my invention,

what I claim is:

1. Ina car truck, the combination of side frames including top,intermediate, and bots tom arch bars, column posts intersecting theoeaaae said arch bars, and a bolster having its ends located between andinterlocked with the said column posts.

2. I11 a car truck, the combination of side frames, includingtop,intermediate, and bottom arch bars, column posts formed integraltherewith and intersecting the said arch bars, and a bolster havingits'ends located between and interlocked with the said column posts.

In a car truck, the combination of side frames including top,intermediate and bottom arch bars, column posts formed integraltherewith and intersecting the said arch bars, lugs formed upon theinner faces of said column posts, and a bolster having its ends formedwith recesses whereby it is interlocked with the side frames.

4. In a car truck, the combination ofside frames, each of which isprovided with a plurality of column posts, and with a plurality ofspring supporting platforms, a

bolster having with said column post-s, and springs seated upon each ofsaid platforms and engaging said bolster.
